Patterning of Polypeptide Thin Films by the Combination of Surface-Initiated Vapor-Deposition Polymerization and Photolithography



A solvent-free strategy offering a fast, economical, and clean approach to integrate polypeptide materials into micrometer-scale devices is presented. The dimensions and compositions can be controlled in both the lateral and vertical directions. The Figure shows a surface-grafted pattern composed of PMLG (poly(γ-methyl-L-glutamate)) and PMLG-b-PBLG, (B indicates benzyl instead of methyl).
